Description

Technical Field

[0001] The utility model relates to the technical field of tree planting, in particular to a cooling device for off-season planting of seedlings. Background Art

[0002] In the off-season planting of seedlings, because they are planted in unsuitable seasons, the evaporation of water from the seedlings will increase, while the root system's ability to absorb water is relatively weak, which may make it difficult for the seedlings to survive due to lack of water. Transpiration inhibitors are a type of chemical commonly used in gardening and forestry. Transpiration inhibitors are mixed with water and diluted and sprayed on seedlings to inhibit the opening of stomata in plant leaves to reduce transpiration losses. The use of transpiration inhibitors not only helps to reduce water evaporation, but also indirectly helps to lower the temperature of the plant body. When plants emit water through transpiration, it is accompanied by energy loss, which is usually manifested as a decrease in leaf temperature. By reducing the transpiration rate, transpiration inhibitors can help maintain a suitable temperature for plant leaves and reduce the potential damage to plants caused by high temperatures. In the off-season planting of seedlings, especially in the high temperature season in summer, the use of transpiration inhibitors can effectively protect seedlings from heat stress and improve the survival rate and growth quality of seedlings.

[0003] Patent document CN209057614U discloses a cooling device for off-season planting of seedlings, "including a bottom plate, the upper end of the bottom plate is fixedly connected to a stirring box, the upper end of the stirring box is provided with a control switch, and the upper end of the stirring box is fixedly connected to a stirring motor. By setting a stirring box, a stirring motor and a stirring blade, the stirring motor is used to drive the stirring blade to rotate, and the liquid inside the stirring box is stirred, without manual stirring, avoiding uneven stirring resulting in uneven spraying of the liquid, which affects the survival rate of the seedlings; by setting a movable rod, a spring button, a telescopic sleeve and a limit hole, the length of the movable rod can be fixed by using the spring button, so that the spraying height can be adjusted, which is convenient for workers to construct and avoids the problem of taller seedlings not being sprayed; By setting a bottom plate, universal wheels and a push handle, the mixing box can be easily moved, reducing the physical labor intensity of the workers. However, the cooling device for off-season planting of seedlings in the above-mentioned public document mainly considers uniformly stirring the liquid medicine through a stirring device, without manual stirring, and the spraying height can be adjusted, which is convenient for workers to construct. It does not take into account that the mixed liquid medicine may also contain solid particles or some sediments that are not completely dissolved. When the liquid medicine is sprayed, these solid particles or sediments contained in the liquid medicine may accumulate at the outlet of the spray pipe, resulting in an increased risk of clogging of the spray pipe head. Therefore, it is necessary to develop a cooling device for off-season planting of seedlings, thereby improving the safety and efficiency of liquid medicine transportation of the cooling device.

A slide groove is symmetrically provided on the inner wall of the connecting pipe, and the slider is slidably arranged in the slide groove. The slider drives the filter to be detachably installed inside the connecting pipe through the slide groove.

[0007] Preferably, sealing strips are fixedly provided at both ends of the connecting pipe, and the sealing strips are made of silicone material.

[0010] Preferably, a buffer pad is provided at the bottom end of the connecting plate, and the top ends of the spring and the damper are connected to the connecting plate through the buffer pad.

[0011] Preferably, a stirring device is fixedly mounted on the top of the liquid storage tank, and one end of the stirring device is passed through the interior of the liquid storage tank, and a water inlet is provided on the top of the liquid storage tank.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is equipped with a filter to facilitate filtering solid impurities in the liquid medicine. When the liquid medicine flows from the liquid storage tank through the water outlet to the spray pipe, the liquid medicine will first pass through the connecting pipe. The filter inside the connecting pipe captures solid impurities in the liquid medicine, preventing the solid impurities from entering the spray pipe. At the same time, the connector uses standard threaded connections with the water outlet and the water pump inlet to ensure a tight connection without leakage. It is also easy to install and disassemble quickly, so that the filter can be regularly checked for contamination and easily removed for cleaning or replaced with a new one when necessary. This effectively prevents blockage of the spray pipe and improves the safety and efficiency of liquid medicine delivery in the cooling device.

[0014] 2. The utility model improves the stability of the cooling device by installing a spring. First, when the cart travels on an uneven ground, the pulley will be impacted, and this impact will be transmitted to the spring. The spring will deform due to its elastic characteristics and absorb part of the energy. At the same time, as the spring deforms, the liquid or gas inside the damper will consume energy due to internal friction, slowing down the rebound speed of the spring and reducing oscillation. Through the coordinated cooperation of the spring and the damper, not only the cooling device is made more stable during driving, and the splashing or uneven spraying of medicine caused by bumps is reduced, but also the adaptability of the cooling device in different environments is improved, and whether it is hard or soft ground, it can maintain good driving performance.
